Former Uncov guy and Persai CEO Kyle Shank, at center, recovers from an unsolicited cupcake smearing by Pownce's Leah Culver. The attack, likely motivated by Uncov accomplice Ted Dziuba's frequent gibes directed at Culver, took place at Flickr's fourth birthday party. Flickr's Cal Henderson, right, is said to have served as Culver's accomplice. Speaking of, can anyone confirm whether Henderson and Culver are dating? The two were inseparable at SXSW. If so, snaps to Culver: We hear Henderson's website is highly scalable. (Photo by magerleagues)
